Which Should You Choose?

Real-world scenarios from our installer experience across Wake County and the Triangle.

If you prioritize smart-home + zoning integration:

Carrier Infinity. Côr thermostat ecosystem + Greenspeed zoning is the most integrated setup on the market.

If you prioritize lowest sound + R-32 refrigerant:

Daikin. 19 dB outdoor unit + R-32 (lower GWP) — important if you have neighbors close or environmental priorities.

If you want strongest warranty:

Daikin (12+12 years vs Carrier's 10 years). Significant on a $15,000 install.

If you've owned Carrier before and like it:

Stick with Carrier. The Côr ecosystem learns your patterns; the upgrade path is easier.

Honest Installer Take

Why We Can Give You a Neutral Comparison

AC Today installs every major HVAC brand — Daikin, Trane, Carrier, Lennox, Bryant, Mitsubishi, Rheem. We're factory-certified for Daikin specifically, but we don't get a kickback for steering you to one brand over another.

When we recommend a system, the recommendation is based on YOUR home's specific needs (size, ductwork, climate, budget, longevity) — not what we earn the most installing.

Common Questions

Is Daikin or Carrier better for NC?+

Both are excellent for NC climate. Daikin's lower noise + better warranty edge it slightly for new installs. Carrier's larger dealer network means faster warranty service if your installer goes out of business.

What's the difference between Daikin Inverter and Carrier Greenspeed?+

Both are continuous variable-speed compressors. Daikin's inverter modulates faster (matches load more precisely). Carrier Greenspeed has 5 stages with smoother transitions. In practice, both feel identical to homeowners.

Can I integrate Daikin with Carrier ductwork?+

Yes — Daikin Fit + Inverter AC + most ducted systems work with standard ductwork from any era. Carrier-branded ductwork is identical to Trane/Lennox-branded — it's all just sheet metal.

Do you install both brands?+

Yes — AC Today is certified for Daikin AND a regular Carrier installer. We give written quotes for both options if asked, with our honest recommendation.
